Example Answer:

This is a very straightforward question you may face and tests your understanding of statistics.

A One-Way Anova is a statistical test that tells you if the dependent variable changes according to the level of the independent variable. You use it when you have collected data about one categorical independent variable and one quantitative dependent variable. The independent variable should have at least three levels (ie. three different groups or categories).

A simple, relatable example is the following:
You want to study the impact of social media use on work performance. You group your employees for social media use in low, medium and high categories and you examine the difference in work performance (ie. lines of code written, tasks complete, etc.). Here social media use is your independent variable with its three levels and the work performance is the measured dependent variable.
